Abstract: A data processing method and apparatus, a device, and a readable storage medium are provided. The method includes: performing figure acquisition on a first object in response to a login operation on an application client, and displaying a first virtual object associated with an acquired object figure of the first object (S101); displaying, in a case that a virtual conversation space is entered by using the first virtual object, one or more virtual objects in the virtual conversation space, the one or more virtual objects including the first virtual object, and a space figure of the virtual conversation space being associated with the one or more virtual objects (S102); and displaying a conversation message corresponding to each of the one or more virtual objects in the virtual conversation space (S103). A virtual object in an application is displayed efficiently in a diversified manner, and virtual object display modes are enriched.

Abstract: A method for generating and compressing multi-sweep-frequency radar signals is provided, based on the idea of reducing the power density of signals on a time-frequency domain. By using a method of circumferentially shifting and superposing a single sweep-frequency signal, sweep-frequency signals multiplexed simultaneously at time and frequency are generated, and for the generated multi-sweep-frequency signals, the sweep-frequency signals are multiplexed simultaneously at time and frequency in a single pulse time period. The multi-sweep-frequency signals multiplexed at frequency are used to perform matched filtering, and then perform segmented accumulation to obtain distance resolution which is inversely proportional to the bandwidth and the signal-to-noise ratio after the single sweep-frequency signal is compressed under the same energy condition, thereby realizing secondary compression on the multi-sweep-frequency signals.
